/ Application filed January 10, 1916. Serial No. 71,374.

To all whom it may concern:

Be it known that I, WALTER citizen of the United States, residing atHumble, in the countyof Harris and State 5 of Texas, have inventedcertain new and useful Improvements in an Oil-Thief, of which thefollowing is a specification.

This invention relates to new and useful improvements in an oilthief. v

The object of the invention is to provide a device of the characteridescribed whereby the oil in a container may be tested.

- "With the above and other objects in View the invention hasparicular'relation to certain novel features of construction, opera-,tion and arrangement of parts, an example of which is givenin thisspecification and illustrated in the accompanying drawings wherein: v v

Figure 1 is a side elevation of. the" device, Fig. 2 is a fragmentaryside elevation thereof, Fig. 3 is a plan view thereof, Fig. 4 is a.

vertical sectional view taken on the line aa of Fig. '1, Fig. 5 is atransverse sectional view taken on the line 6-?) of Fig. 4, Fig. 6 is asectional .view of one of the valves employed, and 7 is a sectional viewof the trip weight, employed.

Referring now more particularly to the drawings wherein like numerals ofreference designate similar parts in each of the figures the numeral 1designates a substantially cylindrical casing, which is formedpreferably of metal casting and is provided with the windows 2, 2 formedof. glass or other transparent material, and arranged opposite eachother, through which the contents of the casing may be inspected.Threaded into the lower end of the casing is the plug 3 AQ-having thecentral passage way 4 whose upper end is flared'forming the seat 5' andthe upper end of the casing has the cap 6 threaded thereon, which hasthe central passageway 7 whose upper-endis flared forming the seat 8 andthreaded upon the'cap 6 is the cage 9, cylindrical in form, and whosepurpose will be hereinafterset forth.

The seat 8 is normallyclosed by the ball valve 10 and the seat 5 isnormally closed 0 by the valve 11, the latter of which being secured tothe valve rod 12 and the former having a limited sliding engagement withsaid valve rod., A transverse .bar 13 is fixed in said casing and has acentral orifice 14 which serves as a guide for said rod and surroundingthe rod and interposed between H. KAUL, a p

the bar 13 and the valve 11 is a coiled push spring 15 through theinfluence of which both of said .valves are normally held against theircorresponding seats. The valve 10.has a limited amount of play relativeto the rod 12 so that the distance between the seats 5 and 8 may beslightly varied and yet each of the valves seat perfectly.

Threaded into thevalve 10 and extending up through the oblong slot 16,cut through the top of the cage 9, is a short rod 17, to the I projectsout beyond the cage.

A hook 19 is pivoted at its lower .end to the. casing 1 and when engagedover said upper end of which the latch 18 is pivoted latch secures therod and valves in elevated position. Projecting at right angles from thelower end of the hook is the flange 20 whose purpose will be.hereinafter set forth.

Attached to the cage 9 is a bail 21 to which a sustaining cable 22 maybe secured and slidable on this cable is the spherical trip weight 23. Atrip rod 24 is provided whose upper end is bent over and formed into aneye 25, through which the cable 22 passes and the lower end of this rodnormally rests upon the flange 20, said rod' passing through an alinedbearing in the top of the cage.

When it is desired to use the device the latch 18 is brought into rightangular position relative to the-rod 12 and the-hook 19 is engagedthe-reover. This will operate to 'unseat the valves 10 and 11 and tocompress the spring 15-. The lower end of the rod 24 is then rested uponthe flange 20 and the de-' vice is then, by the cable 22 lowered thedesired distance into the 011 to be tested.

'Meanwhile the'trip weight .23 is held by the tester until the device islowered to the exact position desired. This weight is then released anddrops down along the sustaining cable until it strikes the upper end ofthe rod .24 and through said 'rod operates to release the hook 19 fromthe latch 18 and the pressure of the spring 15 then operates to' seatthe valve. The casing 1 has, of course, filled with foil and when thevalves are seated this oil will be retained in the device while it isbeing withdrawn, for the purpose of being tested, In large tanks orcontainers the quality of oil varies with the depth of the oil and it istherefore necessary to obtain specimens of the oil at different depthsfor testing purposes and it is for that purpose that the device hereindescribed has been designed. The casing may also be equippedwith athermometer, as 26, of any well known construction, for the purpose ofalso testing the temperature of the oil being tested.

What I claim is:

1. A device of the character described ineluding a receptacle havingopposing inlet passageways surrounded by seats, valves normally closingsaid passageways, a valve 2. A device of the character described, in-

eluding a receptacle, having opposing inlet passageways surrounded byseats, valves normally closing said passageways, means connecting saidvalves, a resilient member in operative connection with said means andtending to hold said valves seated, a latch carried by said means, amechanism pivoted to the device and engaging with said latch and holdingthe valves elevated relative to said seats, and a tripping device fordisengaging said mechanism from said latch and permitting the valves toseat.

In testimony whereof I have signed. niy name to thls specification inthe presence of two subscribing witnesses.

WALTER H. KAUL.
